This was the fifth release in the Destiny Of The Doctor arc, created in cooperation with AudioGo for the 50th anniversary.
The Fifth Doctor takes Tegan, Nyssa and Adric to 1920, where he's agreed to meet up with his old friend Harry Houdini. It's one day before Houdini's famous performance in the water tank. Throughout the Doctor's lives (ever since the Ben & Polly days), he's maintained his friendship with Houdini, but never let him into the TARDIS for fear of messing up the timeline.
While Tegan squees over meeting a legend, Nyssa and Adric try to understand the purpose of the old-fashioned fun fair they're in. Houdini's called the Doctor because a local psychic seems to know a lot more than she should. All his life, Houdini's been searching for evidence of the supernatural, asking the Doctor for guidance — but never finding anything that couldn't be explained with science. The Doctor, for his part, refuses to outright tell Houdini if his quest will ever be successful. The psychic in question turns out to have an alien orb in her tent, which promptly starts showing a pre-recorded psychic message by the Eleventh Doctor. Team TARDIS, guarding the tent, is attacked by lions and tigers and bears (oh my!) while the Doctor is distracted by his future self. Adric manages to hide in a boat contraption (using the powers of maths to calculate his chances). Tegan runs away as fast as she can to distract the animals. Nyssa isn't quite as lucky, and ends up in a theatre tent, where she sees... a hologram of the Master (still in her father's body).
The Doctor, meanwhile, gets a Tap on the Head and wakes up shackled by his hands and feet into Houdini's water tank. He quickly figures out that the Master has been hypnotising the entire fair's crew. To his great disappointment, Houdini (who's responsible for knocking the Doctor out) didn't even need the hypnosis, just some convincing. All his life, Houdini had been searching for a way to know if magic is real, hoping to fulfill a promise he made to his now dead mother: to try and find a way to contact her in the afterlife. Since the Doctor knows the future but refuses to tell him, Houdini's gotten more than a bit angry at his friend and decided to trust the Master.
Adric eventually manages to deduce how the Master's projection gadget works (although he still gets captured a bit by him, as usual). Nyssa, with a lot of encouragement from Tegan, manages to break through her pacifist ways and gathers enough mental strength to shake off the Master's mind control. And the Doctor, who's been thrown into the ocean while still shackled into the water tank, reveals that he nicked Houdini's keys at the start of the adventure when he sensed something was very wrong.
In the aftermath, Houdini apologises and accepts that he's not supposed to know the future. The Doctor explains that it wasn't really the Master, just a psychic projection of him through the alien sphere. He gathers up what's left of the Applied Phlebotinum, as per Eleven's instructions, and ends the adventure merrily riding a wooden carousel horse, to his companions' great confusion.
